I have a little Specialized Hotrock Alloy Frame and Forks for sale, it is a 10" frame and is for 20" wheels.
This will need some serious TLC but would make a lovely bike again as the Frame and Forks are great quality, my son had used and used this bike and it shows, with chips and scratches everywhere. It will also need a new Frame saver as on our last time out at Cannock the rear mech failed and we ended up singlespeeding it for the rest of the day!

Price £25 I can sort posting out which would be around £14.00 but I travel around the country a fair bit so could perhaps drop it off and make it more economical to restore to its former glory. Of course if someone wants to pick it up, then I live between Banbury and Warwick, just off the M40.
This would make a great bike for someone's kid on a budget rather than having to buy a Halfrods clunker.
